9-Step Technical SEO Website Audit Checklist: Updated for 2019

SEO Website Audit

It’s time for your routine SEO website audit.

Hope you’re excited!

Note: An SEO website audit differs from an SEO content audit, in that the latter focuses on analysing and improving the SEO performance of a website's content pages.

Whilst there is some overlap, an SEO website audit zeroes in on specific technical blockers preventing your website as a whole from ranking where it deserves.

There are many articles and guides that teach you how to perform an SEO audit from start to finish.

Like these three:

And they work really well.

However, as they all state clearly and early on - they’re not for the technically inclined.

But you’ll still be spending your time bouncing around a dozen SEO tools to complete objectives.

Btw, just because something is technical doesn’t make it difficult.

That’s a limiting belief.

As long as you’ve got an experienced search marketer by your side, and a guide that shows you how to run a technical SEO website audit and fix the issues - you’re home and dry.

And that’s the purpose of this article.

We’re going to perform an SEO website audit and debug every technical issue that’s preventing your website from ranking as well.

This article will be updated over time as search engines make changes to their algorithms.

But before we do…

1. Run an SEO Website Audit

First thing’s first.

You need to run your website through a comprehensive SEO audit tool.

There are many you can try, often coming with a free trial.

Our two favourites as of writing is SE Ranking and SEO PowerSuite’s Website Auditor.

But for the purpose of this guide, examples and images will be from SE Ranking.

Once you’ve ran an SEO audit on your website, a report will be generated highlighting the severity and number of fixes for you to action.

SEO Website Audit Report - Grow Hack Scale

As you can see, the report is broken down into 8 actions for you to fix over time. They are as follows:

  • Health Check
  • Pages Analysis
  • Meta Analysis
  • Content Analysis
  • Images Analysis
  • Optimization
  • Usability and Technologies

Note: Fixing the issues presented in an SEO website audit report can take weeks or months, depending on the size of your website. We advise businesses to run these routinely (every month), to ensure your fixes are being recognised.

2. Health Check

A website health check is akin to a routine checkup you’d schedule with your local doctor.

The goal here is to ensure there’s nothing obvious standing in the way of your website ranking well on search engines.

A Quick Side Activity

Before you tackle this area, run the following command in Google to see which pages are currently being indexed.

site:[your domain name]

By cross-checking this against your sitemap, you can see at a glance, which are missing (if any) from Google’s index.

This is typically a good place to start. From here, you can use Google Search Console to pin-point exactly why Google's bots won't index your page. Maybe an unintentional “no-index” directive is in place?

Luckily you won't have to guess, as Google tells you why and how to fix them.

Everything look normal here? Let’s more on.

Here’s the most common issues found within a health check report of your website.

WWW Redirect.

URL Rewrite.

Trailing Slashes

Make sure you’re using them correctly → https://www.seroundtable.com/google-trailing-slashes-url-24943.html

Redirect HTTP Traffic to HTTPs.

Robots.txt.

XML Sitemap.

Flash Content.

No Frames.

Common Homepage Variations.

3. Pages Analysis

This section takes a deep dive into the response codes (such as 404) your server sends to a search engine robot, when it attempts a visit. Here, you will also learn how to fix and identify long URLs, pages with large file sizes, improper link attribute usage and much more.

Ultimately, your goal is to have every page you want indexed, to serve an HTTP status code of 200.

HTTP Status Response Codes.

Large Page Sizes.

Long URLs

If you need to keep your URLs long (above 55 characters), then be sure to add breadcrumbs as part of your website’s navigation.

By adding the right HTML markup, your search snippets will change to accommodate this.

Additionally, breadcrumbs help to lower bounce rate. This is because users tend to click on these links to read more resources on your website.

Meta HTML Tags.

Link Attributes.

4. Meta Analysis

This area deals with common on-page duplication issues. Now, to be clear - some content duplication and keyword cannibalisation won’t kill your SEO game. However, it can hurt, especially if the end result is a negative user experience.

Duplicate Page Titles and Meta Descriptions.

Missing Page Titles and Meta Descriptions.

Long or Short Page Titles and Meta Descriptions.

5. Content Analysis

This area of the SEO website audit focuses on content duplication, proper use of heading tags and optimal content length.

Duplicate Content.

Empty and Long Heading (H1 and H2) Tags.

Our Thoughts on Word Count

Good SEO is a lot like good acting. Success isn’t determined by how many lines you get, but  rather by the impact your lines have on your audience.

Take a look at the search results for “Organic Traffic” and “What is Organic Traffic?”.

Omniconvert ranks in both the coveted featured snippets and #1 spot for these terms.

According to Ahrefs, their page generates over 900 visits a month.

With just 120 words.

That’s it!

Now, they also have some very strong backlinks which helps this page rank so well. But the primary reason why it’s gained and retained its spot for so long is because it’s useful to the searcher.

My point is, there’s no need to focus hopelessly on SEO research which analyse the average word count of top ranking pages.

Instead, focus on making your website and content as useful as possible.

Be so good they can’t ignore you.

Whether it takes 100 words or 10,000 doesn’t really matter.

6. Link Analysis

The link analysis section of the SEO website audit focuses on anchor text, linking to quality resources and keeping a well-maintained internal linking strategy.

Excessive Outgoing Links.

Excessive Redirects.

Missing Anchor Text in Internal/External Links.

Improper Usage of Link Attributes

In future updates, we'll cover when to use “no-follow” and “do-follow” attributes in links.

Orphaned Pages and Links.

Dead External Links.

7. Images Analysis

Here, your goal is to ensure there’s a limited number of broken images on your website. Don’t be alarmed if your latest SEO website audit report shows a large number of broken images.

Most often than not, it’s simply alerting you of every instance an image returns as “not accessible.”

For example, let’s imagine that your footer’s logo image is broken.

And you have 200 pages on your website where your footer is displayed.

Your report will state that there are 200 instances of broken images on your website.

By just replacing this image and fixing the issue, you will have solved all 200 instances in one move.

Pretty easy, right?

And the same applies to images that are missing alt-text values.

8. Device Optimisation

Ensuring your website is properly optimised for all devices, goes much further than installing a mobile-responsive Wordpress theme. The impact on your SEO is huge and can no longer be ignored. 

Here’s some core, additional areas of improvement to maintain a good user experience across all devices.

Eliminate Render-Blocking JavaScript and CSS.

Avoid Landing Page Redirects

Usually this issue presents itself at root domain level/your home page. Check what redirects you have set up.

Landing page redirect chain - SEO website audit

As you can see, we’ve accidentally setup a redirect-chain which causes a delay before our website can be loaded.

  • http://growhackscale.com → https://growhackscale.com

Instead, all we need to do is setup one page rule to solve the issue.

  • https://www.growhackscale.com → https://growhackscale.com

Minify HTML, CSS and JavaScript.

Leverage Browser Caching.

Enable Resource and Image Compression.

Prioritise Visible Content.

Reduce Server Response Time.

9. Usability and Technologies

Create a Favicon.

Custom 404 Page.

Increase Website Speed.

Safe Browsing Compatibility.

WC3 HTML Validation.
